Specification of Letters Patent.

Eatented June 19, i908,

Application Eleni November 12, 1904. Serial No. 232.464.

To all whom it may concern:

Be it known that I, HARRY M. ACLY, a citizen of the United States,residinry at Pittsfield, county of Berkshire, State of Massachusetts,

have invented certainnew and useful lm.

,which is simple, strong, and compact, which may be quickly applied andremoved, and

v which is adapted to receive conductors of different sizes.

My invention will best be understood by reference to the accompanyingdrawings, in which- Figure 1 shows a side elevation oi an insulatorarranged in accordance with my invention; and Fig. 2 shows an endelevation of the saine.v

in the drawings, A represents a suitable support adapted to receive theweight of the conductors, and which l have shown as a section of pipe ormetal tubing.

B re resents a U-shaped bolt, with its base twiste to form a loop-in aplane at an angle to the lane of the U, this loop being of a size to titc osely aroundthe pipe A, which hes in the plane oi the U. i

D represents an insulating-block, of porcelain or other suitablematerial, which is provided on its lower surface with a V-shaped grooveadapted to engage the pipe A and is provided on its sides with groovesadapted to engage the legs ofthe U-shaped bolt. When the bolt is placedin position around the pipe and the block D is slipped over the boltinto the position shown, the block and bolt lock each other in ositionready to receive the conductor. T e block D is provided on its uppersurface with a oove at right angles to t at on its lower su ace, adaptedto receive the bus-bar or other conductor C.

E represents a second porcelain block or cap, also provided with lateralffrooves adapted to be engaged by the ends ci? the U-shaped bolt andhaving on its lower surface a V- shaped oove adapted to engage theconductor l) represent nuts carried on the extremities oi the U-shapedbolt, by means of which the clamp E may be clamped in position.

By tightening these nuts the conductor C is firmly clamped between theinsulating-blocks D and E.

What i'claini as new, and desire to secure by Letters Patent or" theUnited States, is

1. In an insulator, a U-shaped bolt having 6o its base bent out of theplane of the U to enn gage a suplport lying in the plane of the U, twodetac able insu ating-blocks having lateral grooves adapted to be enga'ed by the legs of said U-shaped bolt, an means at the ends of saidbolt.

2. In an insulator, a U-shaped bolt lhaving its base bent to form a loopin a plane at an angle to the lane of the U, two detachable insulating-boclrs havin@ lateral grooves 7o A adapted to be engaged by the legs otsaid bolt, and clamping rueans at the ends of said bolt.

3. In an insulator, a U-shapcd bolt having. its base bent out of theplane of the U to engage a support, an insulating-block having 7 5ateral rooves adapted to slide on the legs ot' said bo t and having agroove on its under surface ada ted to engage said support, a second insating-block also having lateral grooves, and clamping means at the endsof 8o said bolt engaging said second blc-ck.

4. lin an insulator, a U-shaped bolt having its base bent to form a loopin a plane at an angle to the plane oi the U, an insulatingblockprovided with lateral Grooves adapted to be engaged by said bolt andhaving grooves on its lower and upper surfaces at right angles to eachother adapted respectively to engagel a support and to receive aconductor, a second insulating-block having lateral grooves 9o and agroove on its lower surface adapted to engage the conductor, andclamping means at the ends of the bolt engaging said second block.

5. ln an insulator, a U-shaped bolt having 9 5 its base bent out oi theplane of the U to engage a support lying in the plane of the Ll, twodetachable insulating-blocks having lateral grooves adapted to beengaged by the legs of said bolt and having il-shaped grooves roo ontheir adjacent surfaces, and clan'iping means at the end ot said bolt.

In witness whereof l have hereunto set my hand this 10th day ofNovember, 1901i.
